The clip comes from Luigi's Mansion, Nintendo's 2001 GameCube launch title starring Luigi, voiced by Charles Martinet. Throughout the haunted mansion, a scared Luigi repeatedly calls Mariooo while searching for his missing brother, and the shaky delivery became one of the game's most quoted moments. The line resurfaced in Let's Plays, Nintendo compilations and TikTok horror edits, where creators use it to signal being lost or abandoned. Its mix of genuine Nintendo nostalgia and exaggerated fear keeps it relevant for gaming memes.
